The spectroradiometer covers dynamic range of luminance level.

It achieves lowest noise and highest accuracy measurement using electro-cooling linear array sensor, unique spectrometry design and signal processing.

#micro LED, OLED, display, LCD, TV

  • High precision spectroscopy method

  • Wide dynamic range of luminance between 0.005cd/m² and 400,000cd/m²

  • Wide spectrum range between 355nm and 835nm complies CIE recommendation

  • Unique optical design to reduce polarization error to < 1% enables high precision testing of DUT having polarization property such as LCD

  • High speed; 1 sec. for standard mode / 20msec for continuous mode

  • Wide luminance range without changing viewing angle(0.005cd/m² ~ 4,000cd/m² at 2°)

  • Stable measurement of pulse drive light source and luminaries

  • Complies reporting format of CIECAM02(Color Appearance Modelling for Color Management Systems)

  • Complies reporting format of CIE2000:2011, taking mesopic vision(Purkinje effect) into consideration
